and useful improvement :in Soldered Rope- Chains", ot which thefollowing is a specilication, reference being had therein to theaeconipanying drawino's.

rl`he vinvention relates to an improvement in that class of chains madeof links oi. metal which are termed rope chains and has specialrei'irence to that class of such chains in which the links are formed ingroups, the links of each group being sol dei-cd togetuer and Yach groupbeing loosely or tlcxibly eonnceted with the adjacent group without anysoldered connection between the groups. ln the manufacture of suchchains il-is necessary to form each link with an open end or breakbetween the ends ol.E the link to enable them to loe strung together,and l lind that in order to obtain the nods-ary flexibility in the Chainit is necessary to string the links together in such a manner thatinstead ol pinching the open ends together to close the'gap after thelinks are assembled the open space referred to between the ends ot' eachlink will he loosely enga-ged by the loop o r closed end ol" one of theconnecting links. l also tind that it the chain is made in groups ofthree links some of the open ends are necessarily exposed and are liableto catch in the clothing or in the lingers in handling the chain insteadof being properly covered up. he object of my invention is to constructa chain of links in such manner that there will be llexible Connectionbetween the ditterent groups of links :1nd that there will be no exposedprojecting ends of the links in each group.

The invention will be fully understood from the following descriptiontaken in connection with the 'accompanying drawings, and the novelfeatures thereoi will be pointed out and elearly'delined in the claimsat the close of this specification.

lo the drawings-litigare l is a plan of a link chain constructed inaccordance with the invention. Fig. 2 is an enlarged view of a portionof the chain shown in Fig. l. Fig. 13 is a view ot one-o the flushed orsolder charged links. Fig. is a detailed View of Speceation of LettersPatent.

Serial No. lthkl` one of the uncharged links. Fig. '5 is a viewof one otthe groups of tour links.

In carrying out the invention l forni each group of links out of foursingle links and preferably iorin the two intermediate links a 'ot' whatis termed charged or flushed wire, c., wire having a coating of solderon the outside torni the two outer links b ot' unehargedil or unflushedWire. Both kinds of links are torni-ed with open ends making anopening-Z which enables the links to be assembled together. lnassembling the links they are so arranged that the links which have theopen end up alternate with the links which have the open end down andalso so arranged that in each group the outermost links, e., those atthe ends of the group will have their open ends eX- iending inwardly,that is, as viewed in Fig.

the uppermost link Z) has the open end' down and the lowerinost link l)has the open end up ,so that there is no exposed open end. Byassembling` thein in this way the closed or loop end ot each link in agroup lies loosely in the open space Z between the ends of one ot' thelinks in another group. There is no possibility ol the links becomingdisengaged and there is no projection of the open ends to catch in theclothing or in the lingers. They are also so arranged that looth of theend links a are of. the uncharged wire and the intermediate links I; areof the charged wire. After the links are assemjbled, then by applyingheat the solder which is inherent in the charged links will he heatedsutliciently so that each adjoining pair of charged links will adheretogether and they will also cause to adhere to themselves the unchargedlinks on. the outer sides olf the charged links, but the two adjacentuneharged links ot' adjoining groups will have no adherence to eachother but are flexibly connected.

W hat l claim is:

l. A soldered rope chain composed of metallic links in groups or" tour,each group consisting ot two solder charged links and two unehargedlinks,.the two charged links ot' each group being contiguous to eaclLother and intermediate between the two uncharged links, each link, bothcharged and nncharged, being an open ring, the links being disposed withthe open ends alternately headed in opposite directions, both nis . @rchgroup having the open' a the four mires ed @gather by i.'
